To all whom it may concern: F v

- Be it'known that I, WILLIAM 'SPALOK- HAVER, a citizen of the United States, residing atNew York, county of Kings, and State of New York, have invented certain new and vusefulZ Improvements in Delivery ltlechanism' for Printing-Machines, fully described and represented in the following specification and'the accompanying drawings, forming a part of the same.

This invention relates to certain improvements in' delivery mechanism for printing machlnes. I

In producing certain folded products on a printing machine, itis desirable, under some u circumstances, to have the folded edge of the product sharply defined, as, for instance, where the printing machine is to produce signatures which are to beafterward put into a collating machine to be assembled for binding.

The present invention has for its object to produce a delivery mechanism for printing machines delivering afolded product by which the folded edge'ofthe roduct is sharply defined. I Vfith this and other objects in View, the invention consists in certain constructions and in certain parts, improvements, and combinations, as will be hereinafter fully described and then specifically pointed out.

Referring to the accompanying drawings-Figure l isa diagrammatic sectional side elevation of so muchof a delivery mechanism of a printing machine-asis necesto an understanding .of 'the invention.

Fig. 2 is an end elevation of theconstruction,

illustrated in Fig. 1.v i

Referring to said drawings, which illustrate one embodiment of the invention, 1 represents a tucking cylinder of ordinary type from which the sheets are delivered by means of a tucking blade, ,indicated'at 2 in dotted lines, to. a pair 'of' tucking-jaws 3, these jaws being mounted on an ordinary folding cylinder 4.- The type *of foldingmechanism just described is well-known in the art, and a specific description of its action is unnecessary. The folded sheets are delivered from the cylinder 4: to a forwarding or delivery cylinder 5 mounted .on the shaft 6, the folded edge of the sheets being taken, in the construction illustrated, by grippers 7 operated in the usual manner, by means of a,

lever 8, cam 9, and spring rod. 10. It has the product. being handled is-either athick product or. consists .of a good quality of heavy paper, or both, that the fold produced, by the folding mechanism'iisinot sufficiently defined for certain purposes, as; for instance, where the signatures are to be operated upon by a collating'machine. "Means are, therefore, provided forLsharpening and defining thefold. Whilethese means may be varied widely in construction, inthe particular machine illustrated, they include an abutment 11 which underlies :the sheet at its folded edge. Suitable cooperating pressing devices which may be varied 'inconstruction will be used. in connection; with this abutment when the abutment is employed. 5 In the particular construction illustrate.d,"these cooperat to straddle the gripper fingers 7'as they pass them. vIfdesired, these rollsg12 and13 may,

be driven. In the construction illustrated, the rolls -12 are;rnounted on a shaft 14: and the rolls 13 are mounted on a shaft 15. [The shaftla is shown as provided witha gear 16 whichis in mesh with a gear 17 mounted on the cylindershaft 6 and the shaftl5 is provided with ajsimilar gear 18; which is also, in mesh withthe gear 17 y J v In the best constructions,-the pressing vices willbe madeadjustable, so that the pressing eif'ec'twmay be exactly defined; In

the; particular machine illustrated, the shaft 14: is mounted Zinhangers. 19, "depending from. an angle, or brace-bar 20 supported in thel-side. frames of the -machinel The hangers 19 are secured to the 'bar20, by means of'bolts 21,,01 infe any other suitable;

'i'nanner, the hangers fbeingslottedgsoas to make the shaft i'a'nd rolls adjustableyertically. If desired, stop screws 22 provided with lockl nuts 23 maybe? employed to prel ve'nt any shifting of the rolls.- Similarly,

the shaft 15 is supported in hangers 24 secured to the brace-bar by means of bolts 25, stop screws 26 being employed in connection therewith. Y

The particular machine shownis provided with a slitting mechanism of usual type, the slitter being marked 27 Itis mounted on a shaft 28 drivenby a gear 29 "meshing with a sans PATENT F op'eeating-fonth'e folded edge of the sheet gear 80 on the shaft 6. The shaft 6 may be driven in any suitable manner, as by a gear 31 which meshes with any suitable driving gear. The sheets may be delivered from the forwarding cylinder in any suitable manner. As shown, the pressedsheets are stripped from the cylinder by means of strippers 32 and fall into receiving compartments in a chain receiver 33 of usual construction.

Changes and variations may be made in the construction by vwhich the invention is carrled'lnto efiect; The lnvention is not;

therefore-to be limited to the particular construction above described and illustrated in the accompanying drawings.

. Thatis claimed is 1;Ii1 a delivery mechanism, the combination-.with means for folding a sheet, of a cylinder to which the folded sheet is delivered, said cylinder having means for forwardingthe sheet, .and means for pressing asubsta-ntial portion of the folded edge of the sheet while on the cylinder whereby the 'fold is sharpened- 25"- warding; the sheet, and a roll-pressure mechanism cooperating with the cylinder to press a substantial portion of and thereby to sharpen the folded edge of the sheet.

eLiIn a delivery mechanism, the combina tion with means for folding a sheet, of a forwarding icyli'nde'r having grippers operatingon the folded edge of the-sheet, and means ope'rating on a substantial portion of the folded edge of the sheet between the grippers wherebythe fold is sharpened.

' 5.? In a delivery mechanism, the combination wiftlrmeans for folding a sheet, of a forwardingcylinder-having grippers operating on 'a;substanti al portionof the folded edg'e of the sheet, and a plurality of rolls between the grippers whereby the fold is sharpened.

6. In a delivery mechanism, the combination with means for folding a sheet, of a forwarding cylinder having grippers operating on the folded edge of the sheet, and a plurality of adjustable rolls operating on the folded edge of the sheet between the grippers tosharpen the fold.

7. In a delivery mechanism, the combination with means for folding a sheet, of a forwarding cylinder having grippers operating on the folded :edge of the sheet, an abutment underlying the sheet near its folded edge, and a plurality of adjustable rolls operating on the folded edge of the illeet between the grippers to sharpen the old.

S. In a delivery mechanism, the combination with means for folding a sheet, of a forwarding cylinder having grippers operating on the folded edge of the sheet, and a plurality of sets of pressure rolls to which the sheets are presented in succession, the rolls operating on the folded edge of the sheet between the grippers to sharpen the fold.

9. In a delivery mechanism, the combination with means for folding a sheet, of a forwarding cylinder having grippers operating on the folded edge of the sheet,

and a plurality of sets of adjustable pressure rolls to which the sheets are presented in succession, the rolls operating on the folded edge of the sheet between the grippers to sharpen the fold.

10. In a delivery mechanism, the combination with means for folding a sheet, of a forwarding cylinder having grippers for operating on the folded edge of the sheet, an abutment underlying the sheet near its folded edge, and a plurality ofsets of adjustable rolls towhich the folded edge of the sheet is presented in succession, the rolls operating on the folded edge of the sheet between the grippers to sharpen the fold.

In testimony whereof, I have hereunto set my hand, in the presence of two subscribing witnesses.
